Specification of Letters Patent.

Application filed November Z6, 1900. Serial No. 87,784.

Be it known that I, CHARLES THIBODEAU, of Somerville, in the county of Middlesex and State of Massacl'iusetts, have invented cer- I tain new and useful Improvements in Candy- Pulling Machines, of which the following is a specification.

This invention relates to a novel machine for pulling candy, such as molasses candy ro and other kinds, and it consists in certain novel features of construction and arrangement, fully described in the specification, clearly illustrated in the drawings and particularly pointed out in theV claims.

Of the accompanying drawings, forming a part of this specification,-Figure 1 repre-` sents an end elevation of a candy-pulling machine constructed in accordance with my invention. Fig. 2 represents a plan view 2o thereof. Fig. 3 represents a side-elevation.

Figs. 4 to 13, inclusive, represent diagram- Lmatic views, showing different positions of the working parts of the machine.

The same reference characters indicate the same parts in all of the figures. Referring to the drawings, which show an embodiment of my invention selected by me `for the purpose of illustrating the invention, 1, 2, 3 and 4 represent four substantially pargo allel pins secured to levers 5, 5. The levers 5 aresecured to the inner ends of two shafts 6, 6, which are journaled in bearings '7 7 at the upper ends of standards 8, 8, said standards 8, 8 being shown as mounted upon a base 9. Each shaft is provided with a gear 10, which meshes with an intermediate gear or idler 11, the`latter in turn meshing with a gear 12. The two gears 12 areseeured to a .common drive-shaft 13, rotated in any suitable man*v 4o ner, as by means of cone-pulleys 14, 15, and a shifting belt 16, whereby diiferent speeds of the said shaft may be obtained. By the den scribed arrangement of shafts and gearing the levers 5, 5 are rotated in the same direction at an equal speed. Each lever has a short arm 17, and a long arm 18,`at the ends of which arms the pins 1, 2, 3 and 4 are afn iiXed.- The said pins are thus located at unequal distances from their axes of revolution, the pins 1, 3 on the short arms 17 being located 'nearer to the shafts 6, 6 than the pins 2, 4 onjthe longer arms 18.

The pins 1, 2, 3gand 4 and ltheir supporting shafts 6 are so related that the circles described by the pins 1 and 3, which are nearest the shafts 6, 6 do not intersect, while the circles described by the pins 2, 4, which are farthest away from the shafts 6, 6 intersect each other. The result of this construction is a novel action, the successive stages ofv which are represented in Figs. 4 to 13. Figs. 4 to 11 show the positions of the parts at quarter turns of the shafts 6, 6. Fig. 12 shows their ositions at slightly less than a quarter turn From the positions shown in Fig. 11. Fig. 13 shows the positions at slightly more thana quarter turn from the positions shown 1n Fig. 12.

Let it be assumed that an elongated roue or batch 20 of candy has been attached to the pin 1, when the pins are all in one plane and the pins 2, 4 on the long arms of the levers have crossed each others paths; a quarter turn of the shafts will bring the ,parts to the position represented in Fig. 5; another quar ter turn causes the rope ofy candy to overlie the pin 2 of the same set as pin 1, as shown in Fig. 6; another quarter turn bends the rope 20 over pin 2, as shown in Fig. 7 another quarter turn causes the rope tobe donbledon the pins 1, 2, and brings the pin e of the set. on the other bracket underneath the doubled strands, as illustrated in Fig. 8; the next quarter turn brings the parts to the position represented in Fig. 9, in which the doubled rope supported by the pins 1, 2 has been pulled out or stretched into a loop by the pin 4. rl`he next quarter turn brings the pins 1., 3 on the short arms adjacent to each other, with the pinv 3 about to come into action, as shown in Fig. 10. It maybe assumed that the feeding of the'rope of candy is then discontinued and the machine has received its full quo-ta. In the next uarter turn the pins 1, 3 draw away from eac other and pull or stre-tch out the candy between them. In' Fig. l2, which shows the parts just before the completion of the next quarter turn, the pins 2, on the long arms are crossing each'others paths, and the candy, 'which is already in' quadruple strands; is about to be doubled again on each set of pins. i/ftfteY the pins haare.'Alk come into the same plane, the next quarter turn brings them into the position shown in Fig. 13, in which both the pins 2 and e are exerting the action which the pin a is exertm ing in Fig. 9. The next quarter turn brings the parts again to the positions shown in Fig. 10, and the subsequent pulling is a repetition of the action shown inliigs. 10, 11, 12 and 13.

pins l and 4 in the drawings, may be bent or bowed toward their axes of revolution, in order to keep the candy centered on the rods. In the operation of the machine the candy is not necessarily wound on the pins successively, as shown in Figs. 4 to 10, this method being selected merely to clearly illustrate the. action of the machine. The candy may be applied to the machine in any suitable manner. For instance, -when the parts have the positions represented in Fig. 6, the pins 1 and 3 being adjacent, a batch of candy may be wrapped around or molded on said pins 1 and 3 and the machine then started, whereupon, the action illustrated in Figs. 10 to 13 will soon ensue and be continuously repeated. In starting to work a batch of candy, the machine is preferably-run slowly at first, and its speed gradually increased until the normal working speed'has been attained.

In the operation of the machine the candy is alternately and automatically fed to the pins (sce Figs. 9 and ,12), then pulled (sce Figs. S and 13), and then refed and re-pulled repeatedly, this operation continuing until the candy has been pulled to the desired eX- tent. In feeding the candy to each other the revolving pins lap the same so that there isa continuous and alternate lapping and pulling or stretching of the mass. The pins move or revolve in vertical planes so that should the mass of candy stretch due to its weight it will be recovered and re-fed to the pins.

I do not confine myself to the exact construction shown, as various modifications may be made within the scope of the invention, which includes power-driven candypulling pins arranged to movein intersecting and non-intersecting paths, and to automatically feed' and re-fced the candy to each other, and then pull and re-pull the fed and re-l'ed candy. I n. place ofthe pins, I may employ other forms of pulling` members and the levers and pins may be dill'ereiltlyrranged and positioned, so long as they operate in the described way, 'l`he path of motion of the pins may, il' desired, be made that of polygons other than circles.

While the means for moving a part of the pulling members in intersecting circles and a 'part in. non-intersecting circles, and the means l'or automatically vcausing the pulling members to lecd and pull the candy, comprise in the form shown, the two levers with their offset pins and the gearing by which the same are driven, yet said levers and their driving mechanism may be variously ar- 2. In a candy-pulling machine, the combination of a plurality of co-acting sets of pins, said sets having pins mounted for movement, some in intersecting paths and others in non-intersecting paths.
